The invention discloses a torque measurement method for a motor group, and the method comprises the steps: arranging a torque sensor in a motor, the torque sensor comprises a plurality of groups of strain resistors, each group of strain resistors comprises at least two strain resistors, and the two strain resistors are disposed at the two sides of a transmission shaft of the motor respectively; when the transmission shaft of the motor moves, the resistance values of the strain resistors change, and the torque sensor outputs voltage signals of changes of each group of strain resistors; the torque value of the motor is calculated according to the changed voltage signals of the multiple sets of strain resistors; the torque value is stored in a database, and a distorted torque value is searched for and identified in the database. According to the invention, accurate and real-time torque measurement is carried out on the motion motor in a complex industrial environment, distorted torque data can be identified, ear
